461a040d29 - Revised Arachne dot output significantly. It is now based on explicit 
ranking instead of the subgraphs. This will make it easier to layout
  e.g. LaTeX MSCs using the same algorithm.

ccremers
2680a2ca7a - Added rank calculation and output. If the subgraphs are removed, this 
will allow for better positioning of the graphs. It also helps a lot
  for latex output. In fact, latex output is fairly trivial now.

94b3ac7c96 - Added debug code for dot output. 
- Push/pop goals are counted now, making the child parameter obsolete.

d33ec486ce - Modified -l switch to also serve as proof depth limit. 2004-10-14 15:25:28 +00:00
ccremers
ba832159b1 - Added a new prioritylevel for seemingly public keys, but the splice-as 
problem remains.

8b48aade68 - Huge effort to make match type 2 (typeflaw generic) matching work. 
Problem with goals that turn into tuples, will have to be solved.

f5ab30995c - Removed the debugging output. 2004-08-30 22:09:44 +00:00
ccremers
5c90522c55 - Fixed a bug in the pruning algorithm, where intruder runs were also 
checked for agent lists, which is false.

b04bc86185 - Some minor cleanups. 2004-08-30 21:49:51 +00:00

4832e9116c - Added pruning theorem for untrusted actors. 2004-08-30 21:07:45 +00:00
ccremers
d43e3d432f - Ignoring singular variables seems to be a smart choice, although it 
implies that the intruder can generate any type. That is not conform
  the usual semantics. So we either change the usual semantics (wise) or
  we make this choice optional.

02041cfbab - Fixed binding displays.

ccremers
b349b6cef2 - More improvements to the dot output. 2004-08-28 12:42:11 +00:00
ccremers
acb89922f1 - Singular variables need to be bound as well (to ensure ordering is 
correct w.r.t. e.g. nonces, if the intruder cannot construct them.)

4420e06e4e - Ignore choose actions when determining Arachne trace length. 2004-08-27 19:15:24 +00:00
ccremers
957b920b98 - Added extra Arachne check for -r0. 2004-08-27 18:26:19 +00:00
ccremers
17ad6de97b - Semistate printing now reports trace length. 
- Pruning was wrong, so the shortest attack wasn't always found. Now it
  is.
 2004-08-27 18:18:16 +00:00
ccremers
198afa135e - Implemented attack length scanner per claim. Not stored yet. 2004-08-27 18:09:09 +00:00

6ccb09297a - Better prune adherence. 2004-08-27 17:37:43 +00:00
ccremers
f90f16fe93 - Arachne engine now respects --prune=2 (and thus the default setting) 
somewhat. There is no good definition of length yet, so we don't do
  this yet.

ccremers
72d52a6e12 - Key goals now have priority. This strategy yields complete proofs for 
e.g. bke, and reduces states for NSL.
 2004-08-20 10:52:40 +00:00
ccremers
baae7ef94a - The proofs now also show a list of open goals at each step. 2004-08-20 09:53:44 +00:00

- Added note about mirroring model checker semantics.

bd84625ae4 - Fixed some more problems. Seems to be stable, although pruning is not 
sufficient. Investigate bke-broken.

c518e68881 BROKEN 
- Added broken attempt to solve to problem, where a new instance has to
  be bound, but older variables point to role terms, e.g. RV#1->RV.
  What should happen, is that it becomes RV#1->RV#new. I thought of a
  solution, but it is still somewhat broken. Maybe I should ignore any
  mappings of variables such as RV, which might be included.

ccremers
0fee6b5797 - Secrecy claims are now handled fairly okayish, as long as only one 
term is in the claim. This should be tupling-or, really, for
  convenience.

a3828a028f - Fixed the very annoying bug! The problem was in roleInstance for 
Arachne. When a subst was carried out by an Rolename->compoundTerm
  substitution, the compound term was not duplicated, and this caused
  problems at roledef destruction.
